Webber: More to come from Red Bull

Mark Webber thinks there is even more performance to come from Red Bull Racing's RB6 following the car's dominant start to the final pre-season test at Barcelona.

The Australian ended day one nearly a full second clear of the opposition as Red Bull ran several aerodynamic upgrades in Spain. While there will not be many changes to the car between now and Bahrain, Webber expects his team to find even more speed with the package.

"Obviously we put some new parts on the car which helped a lot - and of course the car wasn't in its heaviest form in terms of fuel," he said. "Ok, we used a lot of performance today to get the lap time, but we're still looking to improve before Bahrain.

"We still have problems, so we are not going on holiday tonight. We have more work to do, and we're still improving this car."

Webber also played down the gearbox problem that caused him to stop on track, and he does not expect this year's Red Bull to be plagued with reliability gremlins as it aims to improve on its 2009 season.

"We had one problem today, but apart from that we were faultless," he said. "We were very close to pulling off a beautiful smooth day. Also, to learn about the car sometimes you run parts close to the limit on mileage, which wouldn't be the case on race weekends.

"We had a good year last year with podiums and some wins, but this year we need to raise the bar even higher. We need to achieve more.

"We have to finish as many races as we can, because we're not in a situation where we can get away with DNFs. But we're going to do our best to make the car bombproof, and last year we had the same guys, so I'm very confident that we can get on top of any issues we've had in the last few weeks."
